[LAU] Express card 54 adaptor for a Linux laptop

[Nicola]

Hello everyone,
I'm considering the opportunity to improve my home linux studio based 
buying this laptop http://www.garlach44.eu/it/notebook-galway-15-pollici 
(from a small italian company) with Ubuntu pre-installed (No Microsoft 
licenses to pay!!).
This machine has an express card 54 slot.
I'd like to use a firewire sound card (echo audiofire 8) so i should buy 
a firewire express card 54 adaptor.
Does anybody use it & could tell me if it works properly ?
Can you suggest me some models ?
Thanks in advance
Nicola
